IMPROVEMENT IN HUBS FOR VEHICLE-WHEELS.

Specification forming part of Letters Patent No. 148,96?, dated March 24, 1874 application filed August 11, 1873.

To all whom it may concern.'

Be it known that I, THOMAS T. LUCAS, of Bridgeton, county of St. Louis and State of Missouri, have invented a Wheel for Vehicles, of which the following is a specification:

This invention relates to vehicle-wheels, and especially to the hubband, spoke sockets on the band, hub-core, and the spokes; an d it oonsists in improvements hereinafter set forth.

In the accompanying drawing, Figure l is a vertical transverse section, and Fig. 2 a vertical longitudinal section of the central portion of a vehicle-wheel embodying this invention.

A represents the hub-band; B, the spokesockets thereon; C, the outer ends of the spokesockets; D, the inner portions of the spokesockets; E, the hub-core, and F the spokes. The interior of the hub-band is made full in the middle, as at G, and thus the opening for the hub-core is contracted, so that when the hub-core is driven into the band it will be tightly compressed around the middle portion and securely held in the band, while the en-` larged openings toward the ends of the band permit the core to be readily driven. The band may be otherwise tapered, so as to have the inner end of the hub larger than the outer end. The band has mortises H for the spoketenons, and radially-projcctin g sockets elongated to receive and support the spokes. The sockets lare contracted about the middle, as at K, and enlarged or flaring from the contracted portion toward the outer ends, and also to ward the inner ends, so that when the spokes are driven into the sockets the tenons will be compressed in passing the contracted portions, and their inner ends permitted to expand to lill the inner enlarged portions of the sockets. The outer enlarged portions of the sockets will be strained and firmly filled by the spokes The sockets, mortises, and tenons may be made oval or otherwise. The spokes may have tapering tenons and shoulders to cover the outer ends of the sockets. The hub-band and sockets may be made of malleable met-al, so that not only may the wood, on being forced in, adapt itself to the form of the metal, but also the metal yield to the wood. A portion or all of the spokes may pass into `mortises in the hub-core, or they may all rest upon its surface. The sockets on the band may be so projected as to form a slight dish,77 or set straight in a double row. The band may partly cover the hub-core, or extend to the ends thereof.

l. A hub-band having the interior of the band made full or contracted about the middle, substantially as and for the purpose set forth.

2. A metallic hub-band having the interior of the band made full or contracted about the middle, and havin g proj ectin g elongated spoke-- sockets, with the interior ofthe sockets made `full or contracted about the middle, substantially as and for the purposev set forth.

3. A combined hub-band and spoke-sockets, the interior of the band and the interior of the spoke-sockets bein g 1n ade full or contracted about the middle and ilarin g toward the ends, substantially as and for the purpose set forth.

4. The combination of the contracted band A, having contracted sockets B, the wooden hubcore C, and the spokes F, all constructed substantially as and for the purpose set forth.
